Conversion formula
Gradian to Degree formula: value in deg = value in gon × 0.9.
Degree to Gradian formula: value in gon = value in deg × 1.1111111111111.
How to convert Gradian to Degree
To convert Gradian to Degree, multiply the value in gon by 0.9. This gives the result in deg.
For example, 1 gon = 0.9 deg and 10 gon = 9 deg.
What is Gradian?
Gradian (gon): A full turn is 400 gradians and a right angle is 100; used in surveying. 1 gon = 0.9°; 100 gon = 90°.
What is Degree?
Degree (°): A full turn is 360 degrees and a right angle is 90 degrees. 90° = π/2 rad; 360° = 2π rad.
